Summary

0001717: Crash if playing end of clip

Description

Going to the end of the timeline with movie which last thumbnail is white (like empty frame) causes program crash.

(Cant figure out why some clips are visualized with "white end". All tests are made with a phone camera.)

Additional Information

Program received signal SIGSEGV, Segmentation fault.

Notes
(0005423) walxo (reporter) 2010-07-30 14:00	I've uploaded a test movie with d?scribed problem...

(0005461) ttill (developer) 2010-08-03 11:41	Crashes for me, too. I also have some files with the last frame(s) beeing white, but they do not crash.

(0005817) ttill (developer) 2010-09-12 15:30	I cannot reproduce anymore, so I guess Dan fixed this in MLT somewhere between the MLT 0.5.6 release and now.

(0005834) walxo (reporter) 2010-09-14 01:06	Well-done! Thank you! :)

(0005880) ddennedy (developer) 2010-09-22 05:38	Yes, the first git commit after the 0.5.6 release. 0d8eb5b94dcfadffd8e4d67efd62ec09a0934c7f
